Given numbers are 275, 309, 840, 509

The list of prime factors of all numbers are

Prime factors of 275 are 5 x 5 x 11

Prime factors of 309 are 3 x 103

Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7

Prime factors of 509 are 509

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 275, 309, 840, 509

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(275, 309) = 84975

GCD(275, 309) = ( 275 x 309 ) / 84975

= 275 / 309

= 275

Step2:

LCM(1, 840) = 840

GCD(1, 840) = ( 1 x 840 ) / 840

= 1 / 840

= 1

Step3:

LCM(1, 509) = 509

GCD(1, 509) = ( 1 x 509 ) / 509

= 1 / 509

= 1

So, Greatest Common Divisor of 275, 309, 840, 509 is 1
